Description

[Detailed description of the invention] Industrial applications The present invention relates to an electric cooking device having a plurality of cooking bodies.

BACKGROUND OF THE INVENTION In recent years, cooking appliances that combine a food mixer and a speed cutter have come into use in order to streamline household labor.

Conventionally, this type of electric cooking appliance has generally had a configuration as shown in FIG. That is, as shown in the figure, an electric motor 64 and a speed reduction mechanism 61 are provided in the main body 62, and the first rotary cooking body 63 performs cooking by directly transmitting the rotation of the electric motor 64, and the second rotary cooking body Reference numeral 65 is a device for slowing down the rotation of the electric @ 64 by a speed reduction mechanism 61, and then transmitting the power to perform cooking.

Problem to be Solved by the Invention In such a conventional electric cooker, even when using the first rotary cooking body 54 that does not require deceleration, the deceleration II
There was a problem in that the main body 52 containing @51 had to be taken out and used, which took up space.

Therefore, the present invention prevents the place from being completely destroyed when using the first rotary cooking body that does not require deceleration, and allows cooking to be done safely as in the past when using the second rotary cooking body that requires deceleration. The aim is to provide an easy-to-use electric cooker.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides a main body provided with an electric motor and a closing button for closing an energizing circuit to the electric motor; A speed reducer ms that is detachably placed on the main body in place of the rotary cooking body of 1, is covered with a cover provided with a hole, and is rotationally driven by the electric motor.
Deceleration with! 1! an I structure, a second rotary cooking body that is placed on the speed reduction mechanism and performs cooking by receiving rotation from the speed reduction mechanism; and a second rotary cooking body that covers the upper part of the second rotary cooking body and passes through the hole into the cover and a lid provided with a protrusion for sliding the transmission i structure attached to the transmission mechanism, the closing button is not pressed when the deceleration mechanism is placed, and when the lid of the second rotary cooking body is pushed in, the transmission! ! ! The circuit is closed by bringing the beak into contact with the closing button.

As a means of solving the second problem, the closing button is configured to maintain its pressed state only when the button is pressed into contact.

As a third problem-solving means, a switching lever is provided in the main body to switch between the pressed and held state of the closing button, and the switching lever changes the pressed and held state of the closing button to contact and separation when the first rotary cooking body is used. The configuration is such that the state is changed to a state that is maintained afterward, and that the state is maintained only when the second rotary cooking body is pressed into contact when the second rotary cooking body is used.

The fourth means of solving the problem is to provide a sliding hole on the side of the main body for attaching a part of the switching lever so that it protrudes, and when the deceleration mechanism is mounted, the switching lever can be slid in a substantially horizontal direction by the deceleration mechanism. The state in which the closing button is held can be changed by changing the state in which the closing button is held.

In order to achieve the sixth object, the present invention provides a switch with a protection device that automatically cuts off the circuit when an overcurrent flows in the circuit and a release button that resets the protection device,
When the reducer frame is mounted, the release button is placed outside the reducer body.

A sixth means for solving the problem is to make the shape of the deceleration mechanism body asymmetrical in the horizontal direction, provide a step on the top surface of the main body on which the diseased body of the reducer is placed, and make the step have a similar shape to the side surface of the deceleration body. It is.

Furthermore, the seventh means for solving the problem is that when the deceleration mechanism is mounted, the gap between the fitting hole on the lower surface of the deceleration mechanism and the fitting pawl, which is provided for the fitting pawl on the outer periphery of the output part, is The space between the inner surface of the reduction mechanism and the inner surface is increased.

Function The present invention has the above-described configuration, and when the rotary cooking body is used to solve the first problem, the main body does not include a speed reduction mechanism and is small, so it does not take up much space.

And, when using the second rotary cooking body, it is easy to use! By placing the closed barrel tongue inside the deceleration mechanism and sliding the transmission mechanism using a protrusion on the lid to close the circuit, cooking cannot be done unless the lid is closed. This is what I did.

In addition, the second problem-solving function is that by making the closing button a non-holding type that maintains its state only when it is pushed in, it is possible to turn on and off the electricity in conjunction with the pushing of the shu. be.

The third problem-solving function is to change the closing button to a holding type or a non-holding type using a switching lever.
When using the second rotary cooking body, cooking can be carried out without continuing to press the closing button, and conversely, when using the second rotary cooking body, it is linked to the push-in of the straw.

The fourth problem-solving means works by making the switching lever slide in a substantially horizontal direction, so that the force of the switching lever does not act in the direction of lifting the speed reduction mechanism.

The sixth problem-solving means works by installing a protective device on the switch and placing the release button on the outside of the deceleration iW body to prevent overcurrent from flowing in the circuit. The protection device can be reset and reset without lifting the deceleration mechanism.

The effect of solving the sixth problem is that by making the shape of the deceleration mechanism asymmetrical in the left-right or front-rear direction and providing a step with a similar shape on the top surface of the main body, the mounting direction of the deceleration mechanism can be quickly adjusted when using it. I made it easy to understand.

The effect of the seventh problem solving means is that when the reducer beak is mounted, there is a difference in level from the gap between the fitting hole on the lower surface of the reduction gear W1 provided for the fitting claw on the outer periphery of the output part and the fitting claw. By enlarging the space between the main body and the inner surface of the deceleration mechanism, the output part of the main body and the sensor of the input part of the deceleration W1 can be easily aligned, and noise can be reduced.

Then, the upper part of the rotary cooking body 16 is covered with MlB, and the projection 19 is inserted into the hole 14 by pressing the cover 18, and the transmission mechanism 16 is slid. Then, the transmission mechanism 16 comes into contact with the closing button 6 and is pushed in, thereby closing the circuit, the electric motor 2 rotates, the deceleration is completely stopped, the cutter 17 is driven, and cooking is started. At this time, (capital) 1 of the reducer beak body 9
Since the closing button 6 is arranged in the cutter 17, the circuit cannot be closed unless the lid 18 is closed.
It is safe because it does not rotate.

FIG. 5 shows a further embodiment of the second problem-solving means of the present invention, in which the closing button 6 is urged upward by a spring 21,
Only while the closing button 6 is pressed down, the circuit is closed by descending, and the barb 21, which removes the pressing force, returns it to its original position to open the circuit.

Therefore, when using the second rotary cooking body 16, it is possible to turn on and off electricity in conjunction with the movement of pressing the lid 18.
This is useful for chopping vegetables, which can be cooked better by repeatedly applying electricity for short periods of time.

FIG. 6 shows an embodiment related to the third problem-solving means of the present invention, in which a notch is formed from a holding part 22a that holds the closing button 6 in the pressed state at-ti and a non-holding part 22b that does not hold it. A sliding plate 23 provided with 22 and a leaf spring 24 for biasing the sliding plate 23 are attached to the switch 6. A switching lever 26 for sliding the sliding plate 23 is attached to the main body 1. The switching lever 24 is pushed into the speed reducer frame 9 when the speed reduction mechanism body 9 is mounted, and comes into contact with the sliding plate 23, and the non-retaining portion 22b is located below the closing button 6, and the closing button The pressed state of 6 is not maintained. Furthermore, when the deceleration FM structure 9 is not placed, the holding portion 22a holds the closing button 6 in a depressed position. Therefore, when using the first rotary cooking body 7, cooking can be performed without continuously pressing the closing button 6, and the second rotary cooking body 16
When using this, it is possible to turn on and off electricity in conjunction with the movement of pushing the straw 18, which improves usability. Then, two closing buttons 61, a holding type and a non-holding type, are provided.
There is no need to provide one and the cost can be reduced.

FIG. 7-8 and FIG. 7-B relate to the fourth problem-solving means of the present invention. In this embodiment, the switching lever 26 of the third problem solving means is changed, and the side surface 1a of the main body 1 is
A sliding hole 26 is provided in the switching lever 2 from the sliding hole 26.
A switching lever 26 is attached to the main body 1 using a support shaft 25b as a fulcrum.

Further, the contact portion 26a is inclined so that it can be easily pushed into the main body 1 when the deceleration structure 9 is placed, and the end B25cK of the switching lever 25 is provided with a step for contacting the sliding plate 23. When the deceleration mechanism 9 is placed on the main body 1, the contact portion 25a is pushed by the deceleration mechanism 9, and the contact portion 25a slides in a substantially horizontal direction as a fulcrum of the support shaft 25b'i. Then, the end 25a of the switching lever 25 comes into contact with the sliding plate 23, and the non-retaining part 22b is located below the closing button 6, so that the closing button 6 is not held in the pressed state. Here, by making the sliding direction of the switching lever 26 substantially horizontal, when the deceleration mechanism 9 is placed, the deceleration e
The force that the box body 9 receives is approximately horizontal and does not act in the lifting direction. Therefore, the deceleration mechanism 9 can be placed stably without being pushed up, and can be prevented from shaking.

FIGS. 8, 9 and 10 are examples of the sixth problem solving means of the present invention, in which a protection device 27 is switched to automatically cut off the circuit when an overcurrent flows in the circuit. 6
The reset shaft 27 & of the protection device 27 is connected to the switch 5.

When the deceleration mechanism body 9 is placed on the main body 1, the release button 2
A release button 28 is provided at a position where 8 is on the outside of the deceleration mechanism 9. Therefore, the protection device 27 can prevent overcurrent from flowing in the circuit, and since the release button 28 is arranged outside the deceleration mechanism 9, when the protection device 27 is activated, the deceleration mechanism 9 The protective device 27 can be released by pressing the release button 28 without having to lift it.
It is convenient to reset.

FIG. 11 shows an embodiment made as a means for solving the sixth problem of the present invention, in which the external shape of the reduction gear box 9 is made asymmetrical in the horizontal direction, and the reduction mechanism body 9 is fitted onto the upper surface 1b of the main stop. A step 1C is provided, and the shape of the step 1C is similar to the outer shape of the reduction mechanism shaft structure.

Therefore, when the reducer S 9 is placed on the main body 1, the direction of the gear can be immediately determined by looking at the shape of the step 1c.

FIG. 12 shows an embodiment related to the means for solving the seventh problem of the present invention, in which a fitting hole 29 is provided in the lower surface 9a of the deceleration mechanism body 9 for the fitting claw 2o that projects upward from the main body 1. . When the deceleration mechanism 9 is placed on the main body 1 and fitted into the fitting hole 29t with the fitting claw 20, the step 1C and the deceleration ei are lower than the gap 3o between the fitting claw 20 and the fitting hole 29. Internal surface of the structure 9
The space 31 between b and b is enlarged. Therefore, when the output connector 4 rotates and attempts to center the input shaft 11, the deceleration mechanism? The degree of freedom of $9 is increased, making it easier to align the center. By aligning the centers, noise can be reduced.

More than the effects of the invention, as is clear from the description of the above embodiments, when the first rotary cooking body is used, the main body does not include a speed reduction mechanism and is small, so it does not take up much space. When using the second rotary cooking body, the button for closing the energizing circuit is not pressed on the deceleration Ta signal structure, and the transmission is transmitted by the protrusion provided on the lid.
Since the circuit is closed by sliding the structure and pressing the closing button, it is safe because logic cannot be performed unless the lid is closed.

In addition, by making the closing button a non-holding type that maintains its state only when it is pushed in, it is possible to carry out the important action of energization in conjunction with the pushing of the bushing, making it possible to cook with fine movements.

Furthermore, by switching the closing button between a holding type and a non-holding type using a switching lever, it is possible to cook without holding down the closing button when using the first rotary cooking body, and vice versa. When using the second rotary cooking body, the logic linked to the pushing of the straw can be performed, making it easier to use. Furthermore, since only one closing button is required, the cost can be reduced.

By making the switching lever slide in a substantially horizontal direction, it is possible to prevent the force of the switching lever from acting in the direction of lifting the reduction mechanism structure, which would result in instability when the reduction mechanism structure is placed. This is something that can be prevented.

In addition, if a protection device is installed on the switch, a release button for resetting the protection device is placed outside the deceleration FM signal structure to prevent overcurrent from flowing in the circuit.
The protection device can be reset without lifting the deceleration mechanism.

Furthermore, by making the shape of the deceleration S structure asymmetrical in the horizontal direction and creating a step with a similar shape on the top surface of the main body, the mounting direction of the deceleration mechanism can be easily determined when using it, making it easier to use. There is.

When the deceleration mechanism is mounted, the difference between the level difference and the side surface of the deceleration III structure is greater than the gap between the fitting hole on the lower surface of the deceleration i structure and the fitting claw provided for the fitting pawl on the outer periphery of the output part. By increasing the space between the main unit's output section and deceleration 1! This makes it easier to center the input part of the box and reduces noise.
